Responsive web design is an overall approach to building websites that encompasses web specification standards and flexible design models. The philosophy behind it stems from the desire to make the web accessible to as many devices as possible.Responsive design ensures that a website displays properly on desktops and mobile devices like smartphones and tablets. This relatively simple idea has spawned an entire generation of frameworks and tools like Bootstrap that automate much of the grunt work involved in designing responsive sites.Responsive design enables us to optimize the presentation of a web page for many devices with a single piece of source code. This allows you to create similar experiences across different devices, or tailor a web page for a specific device.Fluid grids enable your design to adapt based on the user’s hardware and software. The main concept behind a fluid (responsive) grid is that the layout adjusts according to the client’s browsing environment.Methods used to create a fluid grid involve sizing content with relative (i.e. percentage) units coupled with the use of CSS media queries. Fixed grids, on the other hand, use absolute units such as pixels or centimeters.Another important part of responsive web design is getting the media to adapt to the browsing environment. Some of the elements on the page may need to be resized, or removed from the display completely for certain devices.Overall responsive web-design serves toward better user experience and visual appeal of the web-page portrayed to the audience.
